Complete flexible solar kit, from 120 W to 720 W
A ready-to-wire solar kit for motorhomes, boats, cabins and off-grid sheds. Each kit combines 120 W monocrystalline flexible modules with a charge controller, PV cable, alligator-clip cable and the branch adapter needed to combine the panels, so nothing else has to be sourced separately except the battery and its fuse.

Choosing the right size
Daily yield depends on latitude and season far more than on the panel brand. As a working rule, each 120 W panel returns roughly 400-500 Wh per day in good summer sun and 120-200 Wh in winter.
- 120-240 W: weekend camper, lighting, phones, laptop, water pump
- 360-480 W: full-time van with a compressor fridge and a small inverter
- 600-720 W: cabin or boat with a larger inverter, induction cooking or air conditioning at midday
Wiring the kit
The branch adapter combines panels in parallel at 18 V, which suits a 12 V battery bank. For a 24 V bank, wire panels in series pairs and use an MPPT controller with the right voltage window. Keep the run to the controller short, use 4 mm2 cable or thicker above 240 W, and always fit a fuse between the controller and the battery.

Frequently asked questions
Is a battery included?
No. The kit covers panels, controller, cables and adapters. Battery and fuses are chosen according to your storage needs.
Can I use the kit on a 24 V system?
Yes. Wire the panels in series pairs to reach the 24 V charging window, or use an MPPT controller rated for the resulting array voltage.
Are the panels really flexible?
They bend up to about 30 degrees, enough for a curved motorhome or boat roof. They must not be folded or creased.
Does the included controller support lithium batteries?
The supplied PWM controller is designed for 12/24 V lead-acid and AGM banks. For LiFePO4 we recommend an MPPT controller with a lithium charge profile.
Can I expand the kit later?
Yes, provided the controller current rating covers the new total. Add identical 120 W panels and step up the controller if needed.
What is the delivery time?
5 to 15 business days worldwide.
